Good afternoon.
There is a table with the following structure:

(This table is a fact table for an olap cube) You
need to write an MDX query to get the following result:

I wrote a query, but there is not enough grouping so that it does not sum up the values ​​in col6 and col7. Tell me how to supplement my request in order to get what I want:

, NonEmpty(CrossJoin({[Dim1].[col1].[col1], [Dim2].[col2].[col2], [Dim2].[col3].[col3]})) on 1
from [Cube]
where ([Dim1].[col1].&[value1])
